Road Sign Math

David Slauenwhite brings this mathematically significant road sign near the summit of Bloss Mountain in Pennsylvania. This sign brings a combination of different signs together along with some of Mr. Slauenwhite’s signature “little white signs”. There is a uniqueness to this sign as well since the segment numbers, which are indicated on those white signs, typically are in increments of 10. This sign is unusual which a segment numbered 4. The 4 was assigned when the western end of SR 2023 was relocated and extended to make room for the new US 15.

The math in this sign is unique for Mr. Slauenwhite. There is no trigonometry. No square roots. Just straight forward simple arithmetic.

Here is the sign at the summit of Bloss Mountain. This sign exists because of the persistence of Mr. Neil Fiske who eventually prevailed over PennDOT to get one erected.
